This application claims the benefit of U.S. Provisional PatentApplication No. 61/794,184 filed Mar. 15, 2013, the disclosure of whichis incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

Various embodiments relate generally to content organization andpresentation with a content management system.

BACKGROUND

Recent technological advancement in capturing and recording imagesinclude features that allow users to capture and record images in rapidsuccession, often within microseconds or seconds of each other, thuscreating large sets of user photos. With the decrease in costs forstorage, users often store a large number of their captured photos bothon their cameras and in remote storage. Instead of reviewing andorganizing photos on the camera or within storage when a user's memoryabout the recently captured photos is still fresh, users simply uploadthe entire set to content management systems to review and organizetheir captured images at a later date.

As the number of photos both on the camera and within storage increases,the task of organizing stored photos becomes overwhelming. Adding to thecomplexity in organizing photos, the user may also have images fromother sources, such as images shared by others and/or from multipledevices, often times captured at events or subject matter of otherphotos stored by the user, but, the photos may not be stored togetherbecause they were uploaded from different sources or at different times.As the number of photos stored for a user both increases and areprovided from multiple sources, organization and presentation of photoswithin a user interface that communicates in a meaningful way whatimages are stored for the user becomes more complex.

Accordingly, there is a need for improved organization and presentationof images.

SUMMARY

Embodiments are provided for organization and presentation of content.In some embodiments, a plurality of images and a plurality of similarityrules for image categorization are received. For each image in theplurality of images, the image from the plurality and each remainingimage from the plurality is compared by: applying each similarity ruleto the image and a remaining image from the plurality to obtain anumeric result, and recording the numeric result for the two images in anumeric representation, the numeric representation embodyingsimilarities found between each of the plurality of images. The numericrepresentation is used as a reference for clustering the plurality ofimages into clusters of similar images, and each image is stored with amarker denoting a cluster to which it has been assigned.

DETAILED DESCRIPTION OF THE DISCLOSURE

Methods, systems, and computer readable mediums for organization andpresentation of photos are provided. Content items managed by a contentmanagement system may be organized and then presented within a userinterface to encourage the user to interact with the system and educatethe user on the content items managed by the content management system.Each content item (e.g., images) may be categorized in accordance withsimilarity rules and organized in to clusters with other content itemsfalling into the same categories regardless of the source of the contentitems. The clustering performed may use metadata associated with thecontent items to more accurately sort the images so that the user doesnot have to rely on memory to sort their own images.

Content items may be clustered on a client device prior to upload to thecontent management system, upon upload to a content management system,and/or any combination thereof. In some embodiments, content items(e.g., thumbnail or other representation for an image) may be displayedwithin the user interface with the other content items from thecorresponding cluster, with an indicator for the corresponding cluster,and/or with a link to navigate to another user interface to display thecluster.

User interfaces may provide a sample of content items managed by thecontent management system displayed within mosaics with rows andcolumns. Each row of a mosaic may have content items (e.g., thumbnailsor other representations) displayed in a temporal sequence. The rows ofthe mosaic may display content items for a particular unit of time(e.g., years, months, days). The sample may be random or pseudo-randomselection of images that are continually updated to ensure that the useris educated about the contents within their account with the contentmanagement system. A user can then select an image from a sampledisplayed within the user interface and navigate to a user interface toview the content items clustered with the selected image.

For purposes of description and simplicity, methods, systems andcomputer readable mediums will be described for a content storage andmanagement service, and in particular, organization and presentation ofcontent items (e.g., images). However, the terms “content storageservice” and “content management system” are used herein to referbroadly to a variety of storage providers and management serviceproviders as well as handling a wide variety of types of content, files,portions of files, and/or other types of data. Those with skill in theart will recognize that the methods, systems, and mediums described fororganizing and presenting content items may be used for a variety ofstorage providers/services and types of content, files, portions offiles, and/or other types of data.

FIG. 1 is an exemplary system for presentation and organization ofcontent in accordance with some embodiments of the invention. Elementsin FIG. 1, including, but not limited to, first client electronic device102 a, second client electronic device 102 b, and content managementsystem 100 may communicate by sending and/or receiving data over network106. Network 106 may be any network, combination of networks, or networkdevices that can carry data communication. For example, network 106 maybe any one or any combination of LAN (local area network), WAN (widearea network), telephone network, wireless network, point-to pointnetwork, star network, token ring network, hub network, or any otherconfiguration.

Network 106 can support any number of protocols, including but notlimited to TCP/IP (Transfer Control Protocol and Internet Protocol),HTTP (Hypertext Transfer Protocol), WAP (wireless application protocol),etc. For example, first client electronic device 102 a and second clientelectronic device 102 b (collectively 102) may communicate with contentmanagement system 100 using TCP/IP, and, at a higher level, use browser116 to communicate with a web server (not shown) at content managementsystem 100 using HTTP. Examples of implementations of browser 116,include, but are not limited to, Google Inc. Chrome™ browser, MicrosoftInternet Explorer®, Apple Safari®, Mozilla Firefox, and Opera SoftwareOpera.

A variety of client electronic devices 102 can communicate with contentmanagement system 100, including, but not limited to, desktop computers,mobile computers, mobile communication devices (e.g., mobile phones,smart phones, tablets), televisions, set-top boxes, and/or any othernetwork enabled device. Although two client electronic devices 102 a and102 b are illustrated for description purposes, those with skill in theart will recognize that any number of devices may be used and supportedby content management system 100. Client electronic devices 102 may beused to create, access, modify, and manage files 110 a and 110 b(collectively 110) (e.g. files, file segments, images, etc.) storedlocally within file system 108 a and 108 b (collectively 108) on clientelectronic device 102 and/or stored remotely with content managementsystem 100 (e.g., within data store 118). For example, client electronicdevice 102 a may access file 110 b stored remotely with data store 118of content management system 100 and may or may not store file 110 blocally within file system 108 a on client electronic device 102 a.Continuing with the example, client electronic device 102 a maytemporarily store file 110 b within a cache (not shown) locally withinclient electronic device 102 a, make revisions to file 110 b, and therevisions to file 110 b may be communicated and stored in data store 118of content management system 100. Optionally, a local copy of the file110 a may be stored on client electronic device 102 a.

In particular, client devices 102 may capture, record, and/or storecontent items, such as image files 110. Client devices 102 may have acamera 138 (e.g., 138 a and 138 b) to capture and record digital imagesand/or videos. For example, camera 138 may capture and record images andstore metadata with the images. Metadata may include creation time,geolocation, orientation, rotation, title, and/or any other attributesor data relevant to the captured image. Metadata values may be stored asattribute 112 name-value pairs, tag-value pairs, and/or any other methodto associate the metadata with the file and easily identify the type ofmetadata. In some embodiments, attributes 112 may be tag-value pairsdefined by a particular standard, including, but not limited to,Exchangeable Image File Format (Exif), JPEG File Interchange Format(Jfif), and/or any other standard.

An organization module 136 (e.g., 136 a and 136 b) may be used toorganize content items (e.g., image files) into clusters, organizecontent items to provide samples of content items for display withinuser interfaces, and/or retrieve organized content items forpresentation. The organization module 136 may utilize any clusteringalgorithm, including, but not limited to, algorithms implementing atleast a portion of the ROCK algorithm and/or any other clusteringalgorithm. The ROCK algorithm is described in Guha, S., et al., “ROCK: ARobust Clustering Algorithm for Categorical Attributes,” Proceedings ofthe 15^(th) International Conference on Data Engineering (ICDE '99),IEEE Computer Society, Washington, D.C., USA, pp. 512-521 (1999). and ishereby incorporated by reference in its entirety. The organizationmodule 136 may be used to identify similar images for clusters in orderto organize content items for presentation within user interfaces ondevices 102 and content management system 100. Similarity rules may bedefined to create one or more numeric representations embodyinginformation on similarities between each of the content items inaccordance with the similarity rules. The organization module 136 mayuse the numeric representation as a reference for similarity betweencontent items to cluster the content items.

In some embodiments, content items may be organized into clusters to aidwith retrieval of similar content items in response to search requests.For example, organization module 136 a may identify first and secondimages are similar and may be group the images together in a cluster.Organization module 136 a may process image files to determine clustersindependently or in conjunction with counterpart organization module(e.g., 140 and/or 136 b). In other embodiments, organization module 136a may only provide clusters identified with counterpart organizationmodules (e.g., 140 and/or 136 b) for presentation. Continuing with theexample, processing of image files to determine clusters may be aniterative process that is executed upon receipt of new content itemsand/or new similarity rules.

In some embodiments, a search module 142 on client device 102 isprovided with counterpart search module 144 on content management system144 to support search for content items. A search request may bereceived by search module 142 and/or 144 that requests a content itemfor a particular date, and the search may be handled by searchingcluster markers of stored images. For example, cluster markers mayindicate an approximate time or average time for the images stored withthe cluster marker in some embodiments, and the marker may be used tospeed the search and/or return the search results with the at least oneimage file of the cluster with particular cluster markers.

Files 110 managed by content management system 100 may be stored locallywithin file system 108 of respective devices 102 and/or stored remotelywithin data store 118 of content management system 100 (e.g., files 134in data store 118). Content management system 100 may providesynchronization of files managed by content management system 100.Attributes 112 or other metadata may be stored with files 110. Forexample, a particular attribute may be stored with the file to trackfiles locally stored on client devices 102 that are managed and/orsynchronized by content management system 100. In some embodiments,attributes 112 may be implemented using extended attributes, resourceforks, or any other implementation that allows for storing metadata witha file that is not interpreted by a file system. In particular, anattribute 112 a and 112 b may be a content identifier for a file. Forexample, the content identifier may be a unique or nearly uniqueidentifier (e.g., number or string) that identifies the file.

By storing a content identifier with the file, a file may be tracked.For example, if a user moves the file to another location within thefile system 108 hierarchy and/or modifies the file, then the file maystill be identified within the local file system 108 of a client device102. Any changes or modifications to the file identified with thecontent identifier may be uploaded or provided for synchronizationand/or version control services provided by the content managementsystem 100.

A stand-alone content management application 114 a and 114 b(collectively 114), client application, and/or third-party applicationmay be implemented to provide a user interface for a user to interactwith content management system 100. Content management application 114may expose the functionality provided with content management interface104. Web browser 116 a and 116 b (collectively 116) may be used todisplay a web page front end for a client application that can providecontent management 100 functionality exposed/provided with contentmanagement interface 104.

Content management system 100 may allow a user with an authenticatedaccount to store content, as well as perform management tasks, such asretrieve, modify, browse, synchronize, and/or share content with otheraccounts. Various embodiments of content management system 100 may haveelements, including, but not limited to, content management interfacemodule 104, account management module 120, synchronization module 122,collections module 124, sharing module 126, file system abstraction 128,data store 118, and organization module 140. The content managementservice interface module 104 may expose the server-side or back endfunctionality/capabilities of content management system 100. Forexample, a counter-part user interface (e.g., stand-alone application,client application, etc.) on client electronic devices 102 may beimplemented using content management service interface 104 to allow auser to perform functions offered by modules of content managementsystem 100. In particular, content management system 100 may have anorganization module 140 for identifying similar content items forclusters and samples of content items for presentation within userinterfaces.

The user interface offered on client electronic device 102 may be usedto create an account for a user and authenticate a user to use anaccount using account management module 120. The account managementmodule 120 of the content management service may provide thefunctionality for authenticating use of an account by a user and/or aclient electronic device 102 with username/password, device identifiers,and/or any other authentication method. Account information 130 can bemaintained in data store 118 for accounts. Account information mayinclude, but is not limited to, personal information (e.g., an emailaddress or username), account management information (e.g., accounttype, such as “free” or “paid”), usage information, (e.g., file edithistory), maximum storage space authorized, storage space used, contentstorage locations, security settings, personal configuration settings,content sharing data, etc. An amount of content management may bereserved, allotted, allocated, stored, and/or may be accessed with anauthenticated account. The account may be used to access files 110within data store 118 for the account and/or files 110 made accessibleto the account that are shared from another account. Account module 124can interact with any number of other modules of content managementsystem 100.

An account can be used to store content, such as documents, text files,audio files, video files, etc., from one or more client devices 102authorized on the account. The content can also include folders ofvarious types with different behaviors, or other mechanisms of groupingcontent items together. For example, an account can include a publicfolder that is accessible to any user. The public folder can be assigneda web-accessible address. A link to the web-accessible address can beused to access the contents of the public folder. In another example, anaccount can include a photos folder that is intended for photos and thatprovides specific attributes and actions tailored for photos; an audiofolder that provides the ability to play back audio files and performother audio related actions; or other special purpose folders. Anaccount can also include shared folders or group folders that are linkedwith and available to multiple user accounts. The permissions formultiple users may be different for a shared folder.

Content items (e.g., files 110) can be stored in data store 118. Datastore 118 can be a storage device, multiple storage devices, or aserver. Alternatively, data store 118 can be cloud storage provider ornetwork storage accessible via one or more communications networks.Content management system 100 can hide the complexity and details fromclient devices 102 by using a file system abstraction 128 (e.g., a filesystem database abstraction layer) so that client devices 102 do notneed to know exactly where the content items are being stored by thecontent management system 100. Embodiments can store the content itemsin the same folder hierarchy as they appear on client device 102.Alternatively, content management system 100 can store the content itemsin various orders, arrangements, and/or hierarchies. Content managementsystem 100 can store the content items in a network accessible storage(SAN) device, in a redundant array of inexpensive disks (RAID), etc.Content management system 100 can store content items using one or morepartition types, such as FAT, FAT32, NTFS, EXT2, EXT3, EXT4, ReiserFS,BTRFS, and so forth.

Data store 118 can also store metadata describing content items, contentitem types, and the relationship of content items to various accounts,folders, collections, or groups. The metadata for a content item can bestored as part of the content item or can be stored separately. Metadatacan be store in an object-oriented database, a relational database, afile system, or any other collection of data. In one variation, eachcontent item stored in data store 118 can be assigned a system-wideunique identifier.

Data store 118 can decrease the amount of storage space required byidentifying duplicate files or duplicate chunks of files. Instead ofstoring multiple copies, data store 118 can store a single copy of afile 134 and then use a pointer or other mechanism to link theduplicates to the single copy. Similarly, data store 118 can store files134 more efficiently, as well as provide the ability to undo operations,by using a file version control that tracks changes to files, differentversions of files (including diverging version trees), and a changehistory. The change history can include a set of changes that, whenapplied to the original file version, produce the changed file version.

Content management system 100 can be configured to support automaticsynchronization of content from one or more client devices 102. Thesynchronization can be platform independent. That is, the content can besynchronized across multiple client devices 102 of varying type,capabilities, operating systems, etc. For example, client device 102 acan include client software, which synchronizes, via a synchronizationmodule 122 at content management system 100, content in client device102 file system 108 with the content in an associated user account. Insome cases, the client software can synchronize any changes to contentin a designated folder and its sub-folders, such as new, deleted,modified, copied, or moved files or folders. In one example of clientsoftware that integrates with an existing content managementapplication, a user can manipulate content directly in a local folder,while a background process monitors the local folder for changes andsynchronizes those changes to content management system 100. In someembodiments, a background process can identify content that has beenupdated at content management system 100 and synchronize those changesto the local folder. The client software can provide notifications ofsynchronization operations, and can provide indications of contentstatuses directly within the content management application. Sometimesclient device 102 may not have a network connection available. In thisscenario, the client software can monitor the linked folder for filechanges and queue those changes for later synchronization to contentmanagement system 100 when a network connection is available. Similarly,a user can manually stop or pause synchronization with Contentmanagement system 100.

A user can also view or manipulate content via a web interface generatedand served by user interface module 104. For example, the user cannavigate in a web browser to a web address provided by contentmanagement system 100. Changes or updates to content in the data store118 made through the web interface, such as uploading a new version of afile, can be propagated back to other client devices 102 associated withthe user's account. For example, multiple client devices 102, each withtheir own client software, can be associated with a single account andfiles in the account can be synchronized between each of the multipleclient devices 102.

Content management system 100 can include sharing module 126 formanaging sharing content and/or collections of content publicly orprivately. Sharing content publicly can include making the content itemand/or the collection accessible from any computing device in networkcommunication with content management system 100. Sharing contentprivately can include linking a content item and/or a collection in datastore 118 with two or more user accounts so that each user account hasaccess to the content item. In particular, the sharing module 126 can beused with the collections module 124 to allow sharing of a virtualcollection with another user or user account. The sharing can beperformed in a platform independent manner. That is, the content can beshared across multiple client devices 102 of varying type, capabilities,operating systems, etc. The content can also be shared across varyingtypes of user accounts.

In some embodiments, content management system 100 can be configured tomaintain a content directory or a database table/entity for contentitems where each entry or row identifies the location of each contentitem in data store 118. In some embodiments, a unique or a nearly uniquecontent identifier may be stored for each content item stored in thedata store 118.

Metadata can be stored for each content item. For example, metadata caninclude a content path that can be used to identify the content item.The content path can include the name of the content item and a folderhierarchy associated with the content item (e.g., the path for storagelocally within a client device 102). In another example, the contentpath can include a folder or path of folders in which the content itemis placed as well as the name of the content item. Content managementsystem 100 can use the content path to present the content items in theappropriate folder hierarchy in a user interface with a traditionalhierarchy view. A content pointer that identifies the location of thecontent item in data store 118 can also be stored with the contentidentifier. For example, the content pointer can include the exactstorage address of the content item in memory. In some embodiments, thecontent pointer can point to multiple locations, each of which containsa portion of the content item.

In addition to a content path and content pointer, a content itementry/database table row in a content item database entity can alsoinclude a user account identifier that identifies the user account thathas access to the content item. In some embodiments, multiple useraccount identifiers can be associated with a single content entryindicating that the content item has shared access by the multiple useraccounts.

To share a content item privately, sharing module 126 can be configuredto add a user account identifier to the content entry or database tablerow associated with the content item, thus granting the added useraccount access to the content item. Sharing module 126 can also beconfigured to remove user account identifiers from a content entry ordatabase table rows to restrict a user account's access to the contentitem. The sharing module 126 may also be used to add and remove useraccount identifiers to a database table for virtual collections.

To share content publicly, sharing module 126 can be configured togenerate a custom network address, such as a uniform resource locator(URL), which allows any web browser to access the content in contentmanagement system 100 without any authentication. To accomplish this,sharing module 126 can be configured to include content identificationdata in the generated URL, which can later be used to properly identifyand return the requested content item. For example, sharing module 126can be configured to include the user account identifier and the contentpath in the generated URL. Upon selection of the URL, the contentidentification data included in the URL can be transmitted to contentmanagement system 100 which can use the received content identificationdata to identify the appropriate content entry and return the contentitem associated with the content entry.

To share a virtual collection publicly, sharing module 126 can beconfigured to generate a custom network address, such as a uniformresource locator (URL), which allows any web browser to access thecontent in content management system 100 without any authentication. Toaccomplish this, sharing module 126 can be configured to includecollection identification data in the generated URL, which can later beused to properly identify and return the requested content item. Forexample, sharing module 126 can be configured to include the useraccount identifier and the collection identifier in the generated URL.Upon selection of the URL, the content identification data included inthe URL can be transmitted to content management system 100 which canuse the received content identification data to identify the appropriatecontent entry or database row and return the content item associatedwith the content entry or database row.

In addition to generating the URL, sharing module 126 can also beconfigured to record that a URL to the content item has been created. Insome embodiments, the content entry associated with a content item caninclude a URL flag indicating whether a URL to the content item has beencreated. For example, the URL flag can be a Boolean value initially setto 0 or false to indicate that a URL to the content item has not beencreated. Sharing module 126 can be configured to change the value of theflag to 1 or true after generating a URL to the content item.

In some embodiments, sharing module 126 can also be configured todeactivate a generated URL. For example, each content entry can alsoinclude a URL active flag indicating whether the content should bereturned in response to a request from the generated URL. For example,sharing module 126 can be configured to only return a content itemrequested by a generated link if the URL active flag is set to 1 ortrue. Changing the value of the URL active flag or Boolean value caneasily restrict access to a content item or a collection for which a URLhas been generated. This allows a user to restrict access to the sharedcontent item without having to move the content item or delete thegenerated URL. Likewise, sharing module 126 can reactivate the URL byagain changing the value of the URL active flag to 1 or true. A user canthus easily restore access to the content item without the need togenerate a new URL.

FIG. 2A is an exemplary flowchart for presentation and organization ofcontent in accordance with some embodiments of the invention. FIG. 2A isa flowchart for organization of a plurality of content items, such asimages, into clusters of similar content items, and each content item isable to be displayed with the similar content items within itsrespective cluster. Although the following flowchart describesorganizing and presentation of images, those with skill in the art willrecognize that the following methods may be performed with other typesof content.

A plurality of images may be received (200) for organization by contentmanagement system 100. For example, an image may be captured andrecorded by a client device 102 and/or another source, and then, bereceived by organization module 136 at client device 102. Processing tocluster images may be performed on the client device 102, the contentmanagement system 100, and/or any combination thereof. For example, thereceived image may be compared with other images for the authorizedaccount to organize the content into clusters at the client device 102.Images on client device 102 may be managed by content management system100, and the image may be identified as a candidate for clustering priorto being uploaded to content management system 100. In some embodiments,the image may be processed with other images uploaded to the contentmanagement system 100 and assigned to a cluster upon upload to thecontent management system 100.

A plurality of similarity rules for categorizing an image may bereceived (200). A similarity rule may provide a way to categorizeimages, and assignment within the category may indicate, for example, asimilarity, a commonality, and/or a link between images that makes theimages candidates for a particular cluster. Similarity rules may bedefined to categorize and link images together as being similar based ontheir metadata (e.g., attribute name-value and/or tag-value pairsassociated with the image), information provided by the user, viewinghistory of the users learned by an exemplary system and informationdetermined about the image from further processing of the image (e.g.facial recognition). In some embodiments, similarity rules may define acategory for images having attributes with a particular threshold valueor having a value within a defined range as compared to another image.

The following table 2.1 provides exemplary similarity rules:

Rule Value Weight (1) Is the difference between the creation times ofthe Boolean 5 two compared images less than or equal to four (1 or 0)hours? (2) Is the difference between the geolocation of the Boolean 1two compared images less than or equal to 1000 feet? (1 or 0) (3) Do thetwo compared images have similar colors Boolean .1 or tone? (1 or 0) (4)Do the two compared images contain at least one Boolean .2 similarperson or similar subject matter? (1 or 0) (5) Do the two comparedimages have the same Boolean .3 camera serial number associated with theimage? (1 or 0) (6) Were the two compared images were taken when Boolean.5 the temperature was the same? (1 or 0)

As illustrated with the table 2.1, the rules may rely on comparison ofattributes or metadata of the images, such as creation time,geolocation, title of image, serial number of camera, temperaturerecorded with image, and/or any other metadata associated with theimage. Rules (e.g., rules 3 and 4) may involve further processing of theimages to determine similar colors, tone, facial recognition, and/orsimilar subject matter. A user may also define their own rules to driveclustering of images. The similarity rules may be viewed as defining asimilarity calculator for the images. Application of the similarityrules may allow for identification of groups of images that have morelinks and commonality, with each other and as a result, may be clusteredtogether. In particular, groups of images that have a greater linkdensity (e.g., a greater concentration of links between images withinthe group) may be clustered together.

As described below, link density may be visualized by with the linksdepicted as lines between images, and seeing the aggregations of links.

In some embodiments, similarity rules may be defined to categorizeimages based on services provided by the content management system 100.For example, similarity rules may be defined to categorize images basedupon who shared the images, an authorized account that shared theimages, and/or whether the images were shared with the user. In anotherexample, the similarity rules may be defined to categorize images basedupon whether the images have been recently updated, a particular versionof an image (e.g. only the first version of an image) and/orsynchronized.

In some embodiments, weights may be associated with each rule to reflectthe relative proportion that the results from application of eachsimilarity rule should be factored in to the clustering results. A usermay define rules, as well as skew results, by setting weights to rules.For example, user defined similarity rules may be weighted to ensurethat a user-defined rule overrides predefined similarity rules. By wayof explanation, a user may define a similarity rule to form a categoryfor all photos that include the terms “Family Christmas Photo” in thetitle, and the user-defined similarity rule may be assigned a weight(e.g., 15) to override other similarity rules.

In another example, as illustrated in table 2.1, in some embodiments,rule (1) based on time may factor more heavily than rule (2) based ondistance between locations for creation of images. Images captured atvarious locations may be grouped together, if captured within a windowof time. By way of further explanation, images captured on a road tripat various locations (e.g., images taken in Marin, San Francisco, andPalo Alto) within a window of time (e.g., four hours) may be groupedtogether, even though captured at locations long distances apart.

To cluster images, a comparison may be performed for each of theplurality of images (202). To perform the comparison for a chosen image,the chosen image from the plurality may be compared to each remainingimage from the plurality (204). FIG. 3A illustrates exemplary images forpresentation and organization of content in accordance with someembodiments of the invention. For example, as shown in FIG. 3A,exemplary image A 302 may be compared to each of the remaining imagesstored for a user account, such as the following images: image B 304,image C 306, image D 308, image E 310, image F 312, image G 314, image H316, and image 1318.

Each similarity rule is applied to the chosen image and a chosenremaining image from the plurality to determine at least one numericresult (206). For example, as shown in table 2.1 above, rules (1) and(2) have a finite set of values available with Boolean result values ofeither True (1) or False (0). In this example, the numeric result is avalue from a finite set of similarity results available with applicationof the corresponding similarity rule. Continuing with the example, whenimage A 302 is compared to image B 304 with application of similarityrule (1), the two images are not found to have creation times that arewithin or equal to four hours (e.g., image A 302 has creation time ofJun. 1, 2011 9:00 am and image B has a creation time of Jun. 13, 201112:05 pm) and the numeric result is “0”/False.

The numeric result for the two chosen images is recorded in at least onenumeric representation (208). The numeric representation embodies theinformation on the similarities found between each of the plurality ofimages. The numeric representation may be a matrix containing theresults of the comparisons. FIGS. 3B and 3C illustrate exemplary numericrepresentations for presentation and organization of content inaccordance with some embodiments of the invention. For example, a subsetof numeric results is illustrated in exemplary matrix 301 in FIG. 3Bwith application of rule (1) and exemplary matrix 303 in FIG. 3C withapplication of rule (2). Continuing with the example, numeric resultsmay be recorded in a matrix numeric representation 301 in column 307 forthe chosen image A 302 and the remaining images from the plurality. Asshown in column 307, image A was not created within or at exactly fourhours of time relative to images B-I. Image A was created on June 1 andimages B-I were created on June 13 (as illustrated in user interface ofFIG. 4). Row 305 for image B 304 provides a result “0” or “False” in thecolumn 307 for image A 302 for the comparison of image A 302 to image B304 indicating that creation time of image A 302 is not within or equalto four hours of creation time for image B 304. As illustrated in FIG.3B and FIG. 3C, comparisons between the same images may not be performedas indicated by the “X” (e.g., 309) in the numeric representationmatrices 301 and 303.

FIG. 3A has links 311 drawn between the images to visualize the numericresults in numeric representation 301 of FIG. 3B for image A-I with theapplication of rule (1). As shown, image A 302 does not have a creationtime within four hours of any of the other images (e.g., values“0”/False in column 307 between images A and images B-I of FIG. 3B) inaccordance with rule (1), and there are no temporal links drawn in FIG.3A from image A as shown by 317. In contrast, image B may have acreation time within four hours or equal to the creation times of imagesB-I as denoted by values “1”/True in column 311 of FIG. 3B. To visualizethe links, image B 304 has links 315 with image C 306, image D 308,image E 310, image F 312, image G 314, image H 316, and image I 318 inaccordance with rule(1) as illustrated in FIG. 3A. FIG. 3A illustrateslinks 313 drawn between the images A-I to visualize the numeric resultsin numeric representation 303 of FIG. 3C for image A 302 withapplication of rule (2).

Continuing with FIG. 2A, if there is a next remaining image (210), theneach similarity rule is applied (206) to ensure each of the remainingimages is compared to the chosen image. As shown in FIG. 3B, thesimilarity rule (1) is applied against the next chosen image (e.g. imageB) and recorded in numeric representation 301 under column 311 in therows for the each of the respective remaining images.

In some embodiments, only applying the similarity rules once and reusingthe numeric results from the comparisons may shorten processing time forthe comparisons. For example, the numeric result “0” in row 305, column307 for the comparison between image A 302 and image B 304 may be copiedto row 319, column 311 for the comparison between image B 304 and ImageA 302.

If there are no more remaining images form the plurality (210), a nextimage from the plurality (212) is chosen, and a comparison is performedbetween the next chosen image and each remaining image from theplurality (204).

Alternatively, if there are no more images from the plurality forcomparison (212), then the at least one numeric representation is usedas a reference for clustering the plurality of images into a selectednumber of clusters of similar images (214).

Any clustering algorithm may be used to cluster the images using the atleast one numeric representation as a reference. In some embodiments,the number of clusters may be predefined for use with particularclustering algorithms, such as a K-means algorithm. The predefinednumber of clusters may be selected based upon the amount of spaceavailable for display of the images, based upon an amount of timedesired for the creation times of the images within clusters to span,based upon metadata of the images, based upon a similarity rule, and/orany other criteria. For example, similarity rule (1) categorizes imagestogether for four hour increments, so for a given day, there may be sixclusters: early morning, mid-morning, late morning, early afternoon,late afternoon, and evening. Continuing with the example, the maximumnumber of available clusters may depend on how many days the creationtime for the images span (e.g., 365 days multiplied by 6). Theclustering algorithm may be provided with input including a maximumnumber of clusters and the at least one numeric representation todetermine clusters for the plurality of images.

In other embodiments, the clustering algorithm may dynamically determinethe optimal number of clusters using the numeric representations withcomparison results for each of the images. In some embodiments, eachimage is initially placed into its own cluster (e.g., by the clusteringalgorithm). In other embodiments, the clustering algorithm may be seededor provided with an initial set of clusters as input, as will bedescribed below with reference to FIG. 2B. Pre-processing may beperformed to determine a set of clusters to shorten the processing timefor the clustering algorithm, and the set may be provided as input tothe clustering algorithm. FIG. 2B, described below, provides anexemplary flowchart for presentation and organization of content inaccordance with some embodiments of the invention that illustratesdetermining a set of clusters. In some embodiments, the set of clustersinput to the system may be clusters determined from earlier processingof a plurality of clusters for a user account, and the process of FIG.2A may be performed for a new set of images to be clustered for the useraccount.

To find the optimal number of clusters, on exemplary the algorithm mayiterate through the clusters and repeatedly attempt to merge the clusteruntil there are no more clusters that can be merged. To identifyclusters that may be merged, the numeric representations are referencedto analyze links or commonality between images in their respectiveclusters and merge the clusters based on the density of links betweenimages found. In some embodiments, the weight associated with the linkor commonality between the images may determine whether the clustersshould be merged.

FIG. 3A provides a way to visualize how clusters may be determined byanalyzing link densities between images. For example, image A 302 may bean image captured at a park on early morning Jun. 1, 2011, image B 304may be an image captured at a restaurant located greater than 1000 feetfrom the park on Jun. 13, 2011 and images C-I may be captured at thesame park on Jun. 13, 2011. In the simplest case, as illustrated, imageA 302 does not have links (as shown at 317), thus 317 denoting thatcreation time for image A is not within or equal to four hours of imageB 304 in accordance with rule (1), and image A 302 does not have links(as shown at 319) with image B 304, thus denoting image A 302 wascaptured at a location greater than 1000 feet from image B 304 inaccordance with rule (2). As a result, image A 302 is not clustered withimage B 304. By comparison, image A 302 is linked not linked to imagesC-I based on time in accordance with rule (1) but is linked to imagesC-I based on location in accordance with rule (2). Although image A 302is linked to images C-I based on location (e.g., captured at the samepark), the link densities (illustrated at 321 and 323) are greaterbetween images C-I for both rule (1) based on time and rule (2) based onlocation, and as a result, image A 302 is clustered on its own, whereimages C-I are clustered together. Similarly, image B 304 is linked toimages C-I based on time (e.g., captured within four hours), the linkdensities (illustrated at 321 and 323) are greater between images C-Ifor both rules (1) based on time and rule (2) based on location, and asa result, image B 304 is clustered on its own, where images C-I areclustered together. As noted above, Clustering results may be skewedbased on the weights of the respective rules. For example, if time basedrule (1) is weighted proportionately higher than location based rule(2), then image B 304 may be in fact clustered with images C-I.

If pre-processing is used as described in FIG. 2B, and is only basedupon time (e.g., clustering images within eight hours of each other),then image B 304 may be initially clustered with images C-I. Continuingwith the example, the clustering algorithm may analyze the linkdensities 321 and 323 between image C-I, and then pull image B from itsinitial cluster because the location was not close enough to warrantclustering it with images C-I.

FIG. 4 illustrates the clustering results in user interface 400 forImages A-I in FIG. 3A with the ROCK algorithm and numericrepresentations depicted in FIG. 3B for rule (1) of table 2.1 and FIG.3C for rule (2) of table 2.1. As shown in FIG. 4, Image A 302 is in acluster entitled “Morning” on Jun. 1, 2011, Image B 304 is in clusterentitled “Early Afternoon” on Jun. 13, 2011, and Images C 306 throughImage 1318 are placed into cluster entitled “Late Afternoon” on Jun. 13,2011.

In an embodiment where weights are employed, Image A 302 may becategorized with Images C 306 through Image 1308 with rule (2) asillustrated in column 317 of numeric representation 303 in FIG. 3C andthe links 313 shown in FIG. 3A, but the “pull” for Image A 302 to be inthe “Morning” cluster may outweigh the “pull” to be in a cluster on June13. Continuing with the example, the weight applied for rule (1) basedon time is “5” whereas the weight applied for rule (2) based ongeolocation of images is “1,” and as a result, time categorization ofrule (1) factored more heavily in clustering of the images than spacecategorization of rule (2). The opposite may be true with image B 304with a weighting of “5” on a time rule (1) because image B 304 may beclustered with images C-I even though the locations for image B 304 andImages C-I were greater than 1000 feet apart.

Continuing with reference to FIG. 2A, each image is stored with a markerfor a corresponding cluster (216). A marker may be any identifier thatallows for identification of the cluster. In some embodiments, theclustering algorithm may define K centroids or geometric means, one foreach cluster, which may be used for each marker. Any attribute of theimages may be selected for computing the geometric mean of the cluster.For example, a date and time may be used for calculating the geometricmean of the cluster. In one embodiment, the marker (e.g., 2011061313)may be a string formed from concatenation of the date (e.g., 2011(year), 06 (month), and 13 (day) for the cluster containing image B“Early Afternoon” on Jun. 13, 2011) and a geometric mean for the cluster(e.g., intra cluster time, hour 13). In this example, the geometric meanor average mean for the cluster is calculated by taking an average ofcreation time hour for the images within the cluster. As such, thegeometric mean may be modified as more images are brought in to thecluster or removed from the cluster. However, the cluster marker meanmay indicate the hour for the bulk of the photos within the cluster.

In some embodiments, by incorporating the geometric mean for the cluster(e.g., denoting the date and time to the hour for the bulk of the imageswithin the cluster), the number of modifications to the marker for mostimages may be reduced. By way of example, if the bulk of the images(e.g., 100 images with hour 13) within a cluster are at hour 13, thenplacement of a low number of images into the cluster with a differenthour (e.g., 5 images with hour 12) will not alter the mean, and as aresult, not alter the marker for the majority of the images (e.g., 100images with hour 13), assuming that the placement of the images with thedifferent hour were reclustered and provided with a new marker. Thereduction in the number of marker/identifier modifications may bepreferable for other services provided by the content management system100.

By way of example, if the marker is relied on for caching, then lessmodifications to markers for the bulk of the images may be preferablefor caching techniques. Continuing with the example, if 100 images for acluster were pre-loaded to a cache on a client device for a particularmarker and 5 images were added to the cluster for the particular marker,then the 5 images may not alter the mean and the marker. As such, the100 images may remain with the same marker name within the cache and notrenamed with the introduction of the new 5 images.

In some embodiments, the marker may be used to search for images withina particular cluster by querying the database. For example, a searchrequest may be received through a user interface to retrieve images in“early afternoon” on June 13^(th), and a query may be executed againstthe database to retrieve images stored with a marker “20130613”concatenated with 11, 12, or 13, respectively to find images captured inearly afternoon (e.g., handling hours 11:00 am, noon, and 1:00 pm). Thequery may return results for execution against the database and returnany images within clusters having markers 2012061311, 2012061312,2012061313.

FIG. 2B is an exemplary flowchart for presentation and organization ofcontent in accordance with some embodiments of the invention. FIG. 2B isan exemplary flowchart for pre-processing a plurality of images into aset of clusters for a clustering algorithm. A plurality of images isreceived and a new cluster is created with a chosen image from theplurality (201). The chosen image may be a first image from a pluralityof images or any other selected image from the plurality. For each ofthe remaining images (203), comparisons are performed to cluster similarimages.

To perform comparisons, in some embodiments, a timestamp for the imagein the cluster may be compared to a timestamp of a next remaining imageto determine whether the times are within a time threshold (205). Thetime threshold may be a period of time between the two times accordingto the timestamps. For example, if the times for the images are withineight hours of each other, then the images are within the timethreshold. If the times are not within the time threshold (205), then anew cluster is created with the remaining image from the plurality(209). The process continues if there is a next remaining image (213).

Alternatively, if the timestamps are not within a time threshold (205),then a determination is made as to whether the location for the image inthe cluster and the next remaining image are within a location threshold(207). The location threshold may be a distance between the locations.For example, if the locations are within 125 meters of each other, thenthe images are within the location threshold. If the times are notwithin the location threshold (205), then a new cluster is created withthe remaining image from the plurality (209). If there is a nextremaining image (213), then the comparisons continue (205).

If the locations are within the location threshold (207), then theremaining image is added to a current cluster (211). If there is a nextremaining image (213), then the comparisons continue (205).Alternatively, if there are no more remaining images for comparisons(213), then the process ends. The pre-processing may produce a set ofclusters with similar images to shorten the processing time of theclustering algorithm.

In some embodiments, pre-processing may be performed to recluster asubset of clusters. For example, if a new set of images are received tobe organized within clusters, images from the current set of clustersfor the account that may be affected (e.g. a subset of clusters withmarkers denoting an average hour for the cluster within a certain periodof time from creation time of the one or more new images) and the newimages may be pre-processed to create a set of clusters for the clusteralgorithm. The unaffected current set of clusters and the new clustersformed from the reclustering may be provided as input to the clusteringalgorithm.

FIG. 4 is an exemplary user interface for presentation and organizationof content in accordance with some embodiments of the invention. In userinterface 400, clusters are shown with images (e.g. Image A 302) fromthe cluster (e.g., “Morning” with one image Image A 302) for each of thedays displayed in rows on the display. A search text box 402 is providedto enter a search query and user interface control 404 provides forsubmitting the request. Any type of search may be supported, such asnatural language search and/or semantic search. As shown in FIG. 4, atemporal sequence of images that display a sample from each of theclusters may be displayed. For example, on Jun. 13, 2011, a sample ofseven images from cluster entitled “Late Afternoon” may be selected fromthe 10 available images in the cluster. Sampling is described in moredetail below with FIG. 5.

FIG. 5 is an exemplary flowchart for presentation and organization ofcontent in accordance with some embodiments of the invention. FIG. 5depicts a flowchart for presenting a sample of images for display. Thesample may be a random or pseudo-random selection of images forpresentation to the user. In some embodiments, the images may beselected as “cover” photos for further navigation to a clustercontaining the “cover” photo, and the images may be selected to attractor encourage the user to navigate to clusters to explore their storedcontent. Processing to cluster images may be performed on the clientdevice 102, the content management system 100, and/or any combinationthereof. A plurality of images may be received (500). The plurality ofimages may be designated for management by the content management system100 and stored within the content management system 100, client device102 and/or any combination thereof. The plurality of images (502) may besorted in chronological order (502). By sorting the images inchronological order based on creation time, a temporal sequence ofimages for a sample may be selected. In some embodiments, fuzzy datehandling is supported. For example, an image that does not have acreation time or is assigned a partial date may be corrected by the userby allowing the user to specify a date. Although sampling is describedas using sorting in chronological order, those with skill in the artwill recognize that sorting may be performed using an algorithm. Forexample, the images may be sorted alphabetically based on the titles ofthe images stored in the metadata.

The plurality of images may be divided into groups selected for displaywithin a mosaic on a user interface (504). The mosaic may be a grid withrows and columns of images selected from each of the groups. The numberof groups may be determined based upon the amount of space availablewithin a mosaic and/or the number of groups may be determined based upona unit of time displayed within a row or a column of the mosaic. Forexample, the mosaic may have twelve rows (one for each month of a year)and the plurality may be divided into twelve groups for each year.Continuing with the example, the columns for each row of the mosaic maybe determined based upon the amount of room on the display (e.g., onecolumn on a mobile device and ten columns on a laptop display). FIG. 6Aillustrates a user interface 600 with a mosaic 602 having two rows 604and 606 for each row and will be described in more detail below. Inanother example, if the user interface is being displayed on a mobiledevice, than the mosaic may only have four rows of three columns with asample of photos from each month.

Images may be selected from each group and each selected image may bedisplayed within the mosaic (506). To populate the mosaic, images may beselected from a chosen group (508). Images may be chosen based upon anymetadata or criteria associated with the image. The criteria forselecting an image from a group may include, but is not limited to, theattractiveness of the image, an indication that the image contains aperson, an animal, or a particular gender of a person, a timestamp forlast access of the image, and/or a score of popularity of the image.Each image selected may be displayed on a chosen row of the mosaic.

A determination is made as to whether there is a next group and/or nextcolumn within the chosen row for display of images (510). If there aremore columns and groups, then an image is selected from the next chosengroup (508) and the process continues.

Alternatively, if there are no more columns and groups (508), then adetermination is made as to whether there is a next row of the mosaic(512). If there are more rows of the mosaic to populate (512), then animage is selected from a chosen group (508) and the process continues.Alternatively, if there are no more rows of the mosaic to populate(512), then the process ends.

A non-transitorycomputer readable medium containing instructions that, when executed byat least one processor of a computing device, cause the computing deviceto: receive a plurality of images and a plurality of similarity rulesfor image categorization; for each image in the plurality of images:comparing the image from the plurality and each remaining image from theplurality, by: applying each similarity rule to the image and aremaining image from the plurality to obtain a numeric result; andrecording the numeric result for the two images in a numericrepresentation, the numeric representation embodying similarities foundbetween each of the plurality of images; using the numericrepresentation as a reference for clustering the plurality of imagesinto clusters of similar images; and store each image with a markerdenoting a cluster to which it has been assigned.
 12. The non-transitorycomputer readable medium of claim 11, wherein the marker comprises atime and an average mean for the cluster.
 13. The non-transitorycomputer readable medium of claim 11, when executed by at least oneprocessor of a computing device, further cause the computing device tosort the plurality of images by chronological order; divide theplurality of images into a number of groups based on a unit of timeselected for a mosaic displayed within a user interface, the mosaiccomprising rows and columns of images from each of the groups; selectimages from each group and displaying each image within the mosaic;receive a request for selection of an image displayed within the mosaic;and upon receipt of the request, display the selected image and anindicator for a corresponding cluster containing the image.
 14. Thenon-transitory computer readable medium of claim 11, wherein theplurality of similarity rules comprises one or more of (i) a ruledefining a maximum difference between creation time of the two imagesfor comparison, (ii) a rule defining a maximum difference betweengeolocations of the two images for comparison, (iii) a rule for similarcolors or tone, (iv) a rule for similarity of image content, (v) a rulefor a same camera serial number, (vi) a rule for images taken at a sametemperature.
 15. The non-transitory computer readable medium of claim11, wherein each similarity rule from the plurality is weighted inaccordance with a proportion a corresponding rule is factored indetermining clusters.
 16. The non-transitory computer readable medium ofclaim 11, wherein at least one similarity rule from the pluralitycategorizes images based upon at least one of tone, creation time,geolocation, image subject matter, recognized faces within image,camera, temperature, and a user selected attribute.
 17. Thenon-transitory computer readable medium of claim 11, wherein the imagesare clustered based upon link densities identified between the images.18. The non-transitory computer readable medium of claim 11, wherein atleast one similarity rule from the plurality categorizes images basedupon who shared images.
 19. The non-transitory computer readable mediumof claim 11, wherein at least one similarity rule from the pluralitycategorizes images based upon a date of last synchronization of images.20. A non-transitory computer readable medium containing instructionsthat, when executed by at least one processor of a computing device,cause the computing device to: receive a plurality of images; sort theplurality of images by chronological order; divide the plurality ofimages into groups for display within a mosaic on a user interface, themosaic comprising rows and columns of images from each of the groups,and the number of groups is determined based on at least one of a unitof time being displayed within rows of the mosaic and an available spacefor display of the mosaic within the user interface; select images fromeach group and displaying each image within the mosaic, the selectingcomprising: selecting an image from a group based on at least one of ascore for attractiveness for the image, an indication the image containsa person, a timestamp for last access of the image, and a score forpopularity.
 21. A system for organization and presentation of content,the system comprising: one or more processors; and memory containinginstructions that, when executed, cause one or more processors to:receive a plurality of images and a plurality of similarity rules forimage categorization; for each image in the plurality of images:comparing the image from the plurality and each remaining image from theplurality, by: applying each similarity rule to the image and aremaining image from the plurality to obtain a numeric result; andrecording the numeric result for the two images in a numericrepresentation, the numeric representation embodying similarities foundbetween each of the plurality of images; using the numericrepresentation as a reference for clustering the plurality of imagesinto clusters of similar images; and store each image with a markerdenoting a cluster to which it has been assigned.
 22. The system ofclaim 21, wherein said memory contains instructions that, when executed,further cause one or more processors to: sort the plurality of images bychronological order; divide the plurality of images into groups fordisplay within a mosaic on a user interface, the mosaic comprising rowsand columns of images from each of the groups, and the number of groupsis determined based on at least one of a unit of time being displayedwithin rows of the mosaic and an available space for display of themosaic within the user interface; select images from each group anddisplaying each image within the mosaic, the selecting comprising:selecting an image from a group based on at least one of a score forattractiveness for the image, an indication the image contains a person,a timestamp for last access of the image, and a score for popularity.
